The first person credited with measuring the Earth's circumference was the ancient Greek mathematician and astronomer Eratosthenes. He used the angle of the shadow cast by a vertical stick in Syene and Alexandria to estimate the Earth's size with impressive accuracy for his time.

Who was the first person on earths name?
In Christian tradition, the first person on Earth was named Adam. According to the Bible, Adam was the first man created by God.
Who was the first person to calculate the earth circumference?
The first person credited with accurately calculating the Earth's circumference was the ancient Greek mathematician and astronomer Eratosthenes in the 3rd century BC. He did so by measuring the angle of the sun's rays at two different locations and using simple geometry to estimate the Earth's size.
When was earth diameter first estimated?
Eratosthenes of Cyrene (276 BC - 194 BC) was a Greek mathematician, poet, athlete, geographer and astronomer. He made several remarkable discoveries and inventions: he devised a system of latitude and longitude. He was the first person to calculate the circumference of the Earth with remarkable accuracy, and the tilt of the earth's axis.
The first layer of the earths atmosphere touching earths surf?
The first layer of the Earth's atmosphere is called the troposphere, and it is in direct contact with the Earth's surface. This layer is where weather events occur and where most of the Earth's clouds and precipitation are found. Temperature usually decreases with altitude in the troposphere.
Who is the very first person on earth?
According to various religious texts, Adam and Eve are considered the first human beings created by God on Earth.

When was the the circumference of the Earth first measured and by who?
One possible person is Eratosthenes of Cyrene ~230 BC as he was a Greek scientist who calculated the circumference of the Earth, with remarkable accuracy (some values for the "stadia" he used gives a result within 6% of the actual polar circumference). See link for further information
Who discovered the earths curcumference?
The Greek mathematician and astronomer Eratosthenes is credited with calculating the Earth's circumference around 240 B.C. using the angle of the sun's rays at two different locations and the distance between those locations. This method provided a reasonably accurate estimate of the Earth's size.
How do you find out the diameter when you have a circumference?
To get the diameter from the circumference of a circle, just divide by pi (which is 3.1415 to the first 5 digits).
How do find the circumference if you have the area?
If you mean a circle, first find out the radius (circumference = 2 x pi x radius, so you divide the circumference by 2 and by pi).
How do you correctly install screen doors?
